Retaining system for a movable component

1. A retaining system for a movable component on board an aircraft, with the system comprising:

a support structure with a first retaining area and second retaining area;

a movable component;

a retaining device; and

a locking device;

wherein the movable component is movably attached to the first retaining area with the retaining device, and wherein the movable component is configured to be locked to the second retaining area with the locking device;

wherein the locking device comprises at least one movable locking element and at least one locking receptacle;

wherein the at least one movable locking element is configured to be moved between an open setting (S OFF ) and a locked setting (S VER ), wherein the at least one movable locking element engages with the locking receptacle in the locked setting, so that the movable component is temporarily immovably retained, and allows the movable component to move in the open setting; and

wherein the at least one movable locking element is mounted on the second retaining area, and wherein the at least one locking receptacle is mounted on the movable component.

2. The retaining system of claim 1 , wherein the movable component is a door element, and the door element comprises at least one locking receptacle thereon.

3. The retaining system of claim 1 , wherein the movable component is a movable panel element.

4. The retaining system of claim 1 , wherein the support structure comprises a third retaining area and

at least one further movable locking element,

wherein the movable component is configured to be locked in a primary retaining position (H pos1 ) on the second retaining area; and

wherein the movable component is configured to be locked in a secondary retaining position (H pos2 ) on the third retaining area.

5. The retaining system of claim 1 , further comprising: a first plurality of movable locking elements a matching second plurality of locking receptacles.

6. The retaining system of claim 1 , further comprising a temporarily usable seat attached to the movable component.

7. The retaining system of claim 6 , further comprising a locking mechanism configured to only allow the seat to swivel from an essentially perpendicular stowage position into an essentially horizontal operating position if the door is locked.

8. A module for a cabin of an aircraft, wherein the module comprises:

a module interior; and

a wall structure that at least partially envelops the module interior;

wherein the wall structure is configured with at least one retaining system for a movable component on board an aircraft, with:

a support structure with a first retaining area and second retaining area;

a movable component;

a retaining device; and

a locking device;

wherein the movable component is movably attached to the first retaining area with the retaining device, and wherein the movable component is configured to be locked to the second retaining area with the locking device;

wherein the locking device comprises at least one movable locking element and at least one locking receptacle;

wherein the at least one movable locking element is configured to be moved between an open setting (S OFF ) and a locked setting (S VER ), wherein the at least one movable locking element engages with the locking receptacle in the locked setting, so that the movable component is temporarily immovably retained, and allows the movable component to move in the open setting; and

wherein the at least one movable locking element is mounted on the second retaining area, and wherein the at least one locking receptacle is mounted on the movable component.

9. An aircraft, with:

a fuselage structure; and

a cabin area situated in the fuselage structure;

wherein the cabin area comprises at least one module from the group comprising lavatory, washroom, stowage space, closet, relaxation space, monument, onboard kitchen and staircase; and

wherein the at least one module comprises:

a module interior; and

a wall structure that at least partially envelops the module interior;

wherein the wall structure is configured with at least one retaining system for a movable component on board an aircraft, with:

a support structure with a first retaining area and second retaining area;

a movable component;

a retaining device; and

a locking device;

wherein the movable component is movably attached to the first retaining area with the retaining device, and wherein the movable component is configured to be locked to the second retaining area with the locking device;

wherein the locking device comprises at least one movable locking element and at least one locking receptacle;

wherein the at least one movable locking element is configured to be moved between an open setting (S OFF ) and a locked setting (S VER ), wherein the at least one movable locking element engages with the locking receptacle in the locked setting, so that the movable component is temporarily immovably retained, and allows the movable component to move in the open setting; and

wherein the at least one movable locking element is mounted on the second retaining area, and wherein the at least one locking receptacle is mounted on the movable component.

10. A method for locking and releasing a movable component on board an aircraft, wherein the method comprising:

a) providing a support structure with a first retaining area and a second retaining area;

b) providing a movable component, which is movably attached to the first retaining area with a retaining device, and is configured to be locked on the second retaining area with a locking device, wherein the locking device comprises at least one movable locking element and at least one locking receptacle;

c) moving the at least one movable locking element between an open setting and a locked setting, so as to temporarily lock or release the movable component; wherein the at least one movable locking element engages with the locking receptacle in the locked setting, so that the movable component is temporarily immovably retained, and allows the movable component to move in the open setting; and wherein the at least one movable locking element is mounted on the second retaining area, and wherein the at least one locking receptacle is mounted on the movable component.
